Hi Alan

Before commenting on your further advice I have some compression test results.
I went down to the local Autozone and bought four Sparkplug antifoulers, and I stacked them making an adapter for my compression tester.
The results are as follows:

1. 85psi
2. 102psi
3. 100psi
4. 97.5psi
5. 104psi
6. 105psi
According to the 120psi target, this is bad. Especially 1 is off.
I am positive that the test is performed properly. I checked for leaks and performed all at least twice, with several revs. on each.

I'd really like some feedback on these results. Also if cam timing can have this overall effect on compression, and not just valves and piston(rings).

Alan, if it is still relevant, with the cam timing test you propose, I'll do it, but I am waiting for feedback on this test first.

Thanks once again.
